Su tarea es dar tres idiomas diferentes A, B, C y escribir dos programas diferentes P y Q de manera que:

P es una quine en el lenguaje A, pero no una quine en B ni C;

Q es una quine en el lenguaje B, pero no una quine en A ni C; y

Q concatenado después de P (sin que se agreguen caracteres nuevos) es una quine en el lenguaje C, pero no en B ni A.

Este es codegolf, donde su puntaje es la longitud de la quine final concatenada. Nuevamente, adhiérase a las reglas de quines apropiadas : no leer su código fuente, no hay programas vacíos, etc.

Cómo funciona

Fisión

• R genera un átomo que se mueve hacia la derecha, envolviendo el borde.

• "alterna el modo de impresión. Todo hasta el próximo "está impreso.

• '! establece los átomos en el punto de código de '!'.

• +incrementa la masa del átomo y lo establece en el punto de código de ".

• O imprime el carácter cuyo punto de código es la masa del átomo y destruye el átomo.

CJam

'       e# Push a space character.
